摘　　要：本文对70例肺结核患者的左室功能进行观察和探讨。与单纯肺结核患者相比较,合并肺气肿患者的 LVET 缩短,EF、SWI 和 SV 降低,合并肺心病患者上述指标进一步异常,且 PEP/LVET 明显增加。提示肺结核合并肺气肿或肺心病患者存在着不同程度的左室收缩和泵血功能减退。为探讨机制,将患者分别按右室功能和氧合状态分组分析,右室功能减退组 LVET、PEP、PEP/LVET 和 EF 明显异常。低氧血症组 LVET 缩短,PEP/LVET 增加,EF、SV、CI、SWI 和 CWI 减少。提示低氧血症和右室功能减退是肺结核患者左室功能减退的重要机制。We studied the function of left ventricular in the 70 patients with tuberculosis.Compared with the patients with tuberculosis of non-complication,LVET shortened,EF、SV and SWI decreased in the patients with tuberculosis complicated by emphysema.In the patients with tuberculosis complicated by cor pulmonale,not only the indexes mentioned above were further unnormal,but also PEP/LVET decreased. It suggested that the patients with tuberculosis complicated by emphysema or cot pulmonale existed dysfunc- tion of left ventricular.For researching the mechanisms,the patients were divided into groups respectively ac- cording to the function of right ventricular and oxygenation.LVET、PEP、PEP/LVET and EF were unnor- mal in the patients of dysfunction of right ventricular.LVET shortened,PEP/LVET increased,EF、SV、 SWI、CI and CWI decreased in the patients of hypoxemia.It showed that hypoxemia and dysfunction of right ventricular played an important role in the dysfunction of left ventricular in the patients with tuberculosis.
